I have a function that currently takes a boolean value as a parameter. But now I want to expand it to 3 options... So if I have...function doFooBar($doFoo = false) { if($doFoo) { echo "Did Foo"; } else { echo "Did Bar"; } } Is it as "simple" as changing it like follows to avoid having to change existing code that won't use the new values. function doFooBar($doFoo = 0) { if($doFoo == 2) { echo "Did Baz"; } else if($doFoo == 1) { echo "Did Foo"; } else { echo "Did Bar"; } } Something about that disturbs me. Perhaps because any time I think "Oh it will be as simple as..." it usually isn't. Thanks in advance! Matt
Unless you're doing a strict comparison (===), it probably won't make a lot of difference. However, if you sent "true" to the function, I believe it will reach the last else condition. You may revisit all the locations you call it and update them appropriately.
